They were manufactured in paris, france. The fountain pen has an 18 ct. Gold nib in a fine size. The pens are fluted in gold plate with green caps. Both pens are marked with gold hallmarks with a small serial number etched on the cap clip.
The fountain pen cap is a screw mount. The fountain pen includes the refillable ink converter and also takes standard size cartridges. The pens measure 5 3/8 inches in length (capped). The pens write well and in good used condition, except for some cosmetic marks on the edge of fountain pen cap (see photo highlighting this). The marks might result from of a prior repair (but i do not know) there are no personal engravings and the original presentation case is not included.
